I love white instruments. White with a single ply white guard, a dark tort guard, a single ply black guard, a real nitrate guard (not modern "mint" recreations), classic anodized aluminum gold guard, three ply or five ply black, all look great. The only guards I don't really dig on white instruments are multi ply white ones.
As far as white ones go, I have:
'76 Musicmaster Bass – yellowed white w/ three ply white guard
'85 MIJ Strat - cream white w/ three ply black guard (not stock guard)
AV '58 P - blonde w/ gold anodized aluminum
AV '64 J - Oly White w/ dark tort
AV '64 Tele - blonde w/ three ply white
Jimmy Page Mirror Tele - blonde w/ single ply white
And I am building a '55 hardtail Strat repro at the moment too, which will be painted the same white color as the single ply white guard.
